FIRE WEATHER PLANNING FORECAST FOR PUERTO RICO
NATIONAL WEATHER SERVICE SAN JUAN PR
459 AM AST SUN FEB 8 2026
DISCUSSION
FIRE DANGER WILL REMAIN LOW TODAY, THOUGH A FEW FACTORS WARRANT
MONITORING. BREEZY TO LOCALLY WINDY CONDITIONS MAY DEVELOP, WHICH
WOULD NORMALLY FAVOR FIRE SPREAD, AND KBDI REMAINS ELEVATED AT
CABO ROJO AND CAMP SANTIAGO. HOWEVER, HIGH RELATIVE HUMIDITY,
RECENT ABOVE-NORMAL RAINFALL OVER THE PAST 30–60 DAYS, AND THE
POTENTIAL FOR AFTERNOON SHRA OVER SOUTHERN PUERTO RICO WILL LIMIT
FIRE GROWTH AND SPREAD. NO SIGNIFICANT FIRE WEATHER CONCERNS ARE
EXPECTED.
